AIM:To investigate the effects of electroacupuncture at the Taiyang on refractive parameters and the expression of β-catenin and integrin β1 in the ciliary body of mice with form-deprivation myopia(FDM).METHODS:A total of 48 3-week-old healthy C57BL/6J mice were randomly divided into 4 groups: normal control(NC), FDM group, sham acupuncture(sham), and electroacupuncture at Taiyang acupoint(Taiyang), with 12 mice in each group. Mice in the FDM, sham, and Taiyang groups, wore translucent custom-made eye masks on the right eye to induce myopia. The Taiyang group received electroacupuncture stimulation at the Taiyang acupoint, while the sham group underwent non-penetrating stimulation with a blunt wooden stick. No intervention was performed on the NC group. Refraction and axial length were measured by infrared autorefractor and optical coherence tomography(OCT)before modeling and at 4 wk after modeling. The expression levels of β-catenin and integrin β1 in the ciliary body of mice at 4 wk after modeling were detected using quantitative real-time PCR(qPCR)and Western blotting(WB).RESULTS:After modeling for 4 wk, compared with the NC group, the FDM and sham groups showed significantly decreased refractive power(both P<0.05), elongated axial length(both P<0.05), and increased β-catenin and integrin β1 expression. Compared with the FDM and sham groups, the Taiyang group showed significantly increased refractive power(both P<0.05), shortened axial length(both P<0.05), and decreased β-catenin and integrin β1 expression.CONCLUSION:Electroacupuncture stimulation at the Taiyang acupoint effectively delayed the progression of myopia in FDM mice, and this effect may be partially mediated through modulating the expression of β-catenin and integrin β1 in the ciliary body.

Insulin-like growth factor-1(IGF-1)is a multifunctional growth factor which plays an important role in various physiological and pathological processes of the body by regulating biological behaviors such as cell proliferation, differentiation, and migration. Studies have found that abnormal expression of IGF-1 in the retina, sclera and other eye tissues can participate in the occurrence, development and prognosis of various ophthalmic diseases by regulating retinal autophagy flux and angiogenesis, adipogenic differentiation of orbital soft tissues and degradation of scleral extracellular matrix. This paper systematically integrates the expression level changes and mechanism of action of IGF-1 in ophthalmic diseases such as diabetic retinopathy(DR), age-related macular degeneration(ARMD), retinopathy of prematurity(ROP), Graves' ophthalmopathy, myopia, corneal injury and uveal melanoma(UM), and combines the latest clinical and animal experimental evidence to evaluate the bright prospects and potential risks of IGF-1 targeted therapy, in order to provide new ideas and theoretical basis for the prevention and treatment of ophthalmic diseases.

Objective To explore the status of nursing work engagement, nursing work environment and emotional intelligence and their relationship among nurses who work in hematopoietic stem cell transplantation (HSCT) units. Methods A total of 225 HSCT nurses were selected as study subjects by convenience sampling method. Utrecht Work Engagement Scale, Nursing Work Environment Scale and Emotional Intelligence Scale were used to assess the work engagement, work environment and emotional intelligence among these nurses. AMOS 23.0 software was used to construct the structural equation model. Results The median and 25th and 75th percentiles of the score of work engagement of the research subjects were 59.0 (54.0, 64.0) points. The average scores of the nursing work environment and emotional intelligence were (117.8±21.5) and (58.8±10.7) points, respectively. The score of work engagement was positively correlated with the scores of the nursing work environment and emotional intelligence (rank correlation coefficients were 0.550 and 0.431, respectively, both P<0.01). The total score of the nursing work environment was positively correlated with the total score of emotional intelligence (correlation coefficient was 0.271, P<0.01). The nursing work environment influenced the work engagement status of HSCT nurses through the mediating effect of emotional intelligence, with an indirect effect of 0.115 (95% confidence interval: 0.201-0.365), accounting for 20.4% of the total effect. Conclusion Emotional intelligence is a mediating variable between the nursing work environment and work engagement of HSCT nurses.

The central amygdala (CeA) is a crucial modulator of emotional, behavioral, and autonomic functions, including cardiovascular responses. Despite its importance, the specific circuit by which the CeA modulates blood pressure remains insufficiently explored. Our investigations demonstrate that photostimulation of GABAergic neurons in the centromedial amygdala (CeM^GABA), as opposed to those in the centrolateral amygdala (CeL), produces a depressor response in both anesthetized and freely-moving mice. In addition, activation of CeM^GABA axonal terminals projecting to the nucleus tractus solitarius (NTS) significantly reduces blood pressure. These CeM^GABA neurons form synaptic connections with NTS neurons, allowing for the modulation of cardiovascular responses by influencing the caudal or rostral ventrolateral medulla. Furthermore, CeM^GABA neurons targeting the NTS receive dense inputs from the CeL. Consequently, stimulation of CeM^GABA neurons elicits hypotension through the CeM-NTS circuit, offering deeper insights into the cardiovascular responses associated with emotions and behaviors.

Objective:To investigate the value of elevated preoperative troponin T (TnT) in predicting perioperative adverse cardiac events in geriatric hip fracture patients.Methods:A total of 273 elderly patients undergoing surgical treatment for hip fracture at Department of Cardiology, Tianjin Hospital between January 2024 and December 2024 were enrolled. Basic demographic information was recorded, and preoperative TnT levels were measured. Patients with elevated preoperative TnT ( n=114) were enrolled into the elevated group, while those with normal TnT ( n=159) were enrolled into the normal group. Fracture types included femoral neck fracture ( n=141) and intertrochanteric fracture ( n=132). The impact of elevated preoperative TnT on perioperative major adverse cardiovascular events (MACEs), as well as the influence of different fracture types on MACEs, were analyzed. Normally distributed continuous data were expressed as Mean±SD and compared by independent samples t-test. Categorical data were expressed as case(%) and compared by χ2 test. Multivariate binary logistic regression analysis was performed. The predictive value of TnT for MACEs was assessed by plotting the receiver operating characteristic (ROC) curve and calculating the area under the curve (AUC). Results:The incidence of perioperative MACEs was significantly higher in the elevated TnT group (21.9%, 25/114) compared to the normal TnT group (3.1%, 5/159), with a statistically significant difference ( χ2=23.95, P<0.001). The comparison of postoperative MACEs incidence between different fracture types showed no statistically significant difference [12.1% (17/141) vs. 9.8% (13/132)] ( χ2=0.34, P=0.560). Multivariate binary logistic regression analysis indicated that elevated TnT level ( OR=8.633, 95% CI: 3.117-23.911, P<0.001) was an independent risk factor for perioperative major adverse cardiovascular events (MACEs), increasing the risk by 7.633 times compared to patients with normal TnT. A TnT threshold of ≥0.028 μg/L predicted MACEs with a sensitivity of 0.600 and specificity of 0.954 (AUC=0.839, 95% CI: 0.751-0.926, P<0.05). Conclusion:Troponin T can serve as an independent predictor of perioperative adverse cardiovascular events in elderly patients undergoing surgery for hip fracture and plays a crucial role in the perioperative cardiovascular risk assessment of these patients.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective To evaluate the long-term effects of orthokeratology(ortho-k)lenses with different back optical zone diameters(BOZD)on the quality of vision in myopic children.Methods We conducted an exploratory analysis based on a prospective,randomized,double-blind clinical trial,focusing on the parameters related to visual quality.A total of 66 myopic children aged 8 to 12 years were enrolled and randomly assigned to either a 6-mm BOZD ortho-k lens group(the 6 mm group)or a 5-mm BOZD ortho-k lens group(the 5 mm group).The participants were followed up at baseline,and at 1 day,1 week,and 1,3,6,9,and 12 months after lens wearing.Visual quality measurements included uncorrected visual acuity(VA),best corrected VA,contrast sensitivity(CS),high-order aberrations(HOA),modulation transfer function(MTF),Strayer ratio(SR),and visual quality questionnaire.Results A total of 63 children(33 children in the 6 mm group and 30 children in the 5 mm group)completed the study.There were no significant differences in baseline data between the two groups(P>0.05).There were no significant differences in subjective uncorrected VA or best corrected VA between the two groups at any follow-up visit(P>0.05).After wearing the lenses for 3 months,the CS at high spatial frequency(18 cpd)in the 5 mm group was lower than that in the 6 mm group(P=0.015).However,at 12 months,no significant differences in the CS were found between the two groups(P>0.05).The ocular and corneal total HOA,spherical aberration,and coma aberration in both groups increased after wearing the lenses,and the HOA in the 5 mm group was higher than that in the 6 mm group(all P<0.05).After wearing the lenses for 3 months,the MTF and SR values in the 5 mm group were lower than those in the 6 mm group(P<0.05).At 12 months,there was no significant difference between the two groups(P>0.05).The vision-quality-related questionnaire scores showed no significant differences between the two groups(P>0.05).Conclusion In myopic children,wearing ortho-k lenses with different BOZD results in improved subjective satisfaction,with no difference in subjective visual quality.However,objective visual quality declined in both groups,with a greater impact observed in the 5 mm group.
